I like the idea, how does it affect his interaction with Lois? Earth-3 of the Pre-crisis was like that (sort of) with Lois married to a (good) Alexander Luthor. The only thing is, Clark was still a reporter for their version of the Planet if I recall correctly. What do you think Clark would be involved in in terms of criminality? Maybe something that seems not so black and white?

CLARK: No. I'm just worried I'm a jinx.
JONATHAN: A jinx?
CLARK: Yeah. Let's face it, ever since she's known me, Lois's been kidnapped, frozen, pushed off buildings, almost stabbed, poisoned, buried alive and who knows what else, and it's all because of me.
